Example 2: Low Latency Queue Discipline Enabled
In this example Low Latency Queue Discipline is enabled. CoS1 is not rate controlled (hence the
field is disabled). CoS2 takes 100 kbits when there are no CoS1 packets. CoS6 has 300 kbits
when there are no CoS1 or CoS2 packets. This is similar to the HTB queue discipline as they are
both rate-based algorithm, except that CoS1 is handled differently.
Example 3: PRIOWRR Enabled
In this third example, PRIOWRR is enabled. Since PRIOWRR operates only on the number of
packets being transmitted, the max rate field has been disabled. Only percentage can be
assigned to the CoS2 - CoS6. CoS1 is not rate controlled (hence the field is not displayed). When
there are no CoS1 packets, CoS2, CoS3, CoS4 each has 10 percent, and CoS6 has 70 percent.
This is similarly to the Low Latency Queue discipline, except that one is packet-based, and the
other is rate-based.
